The following table shows the total cost schedule of a competitive firm. It is given that the price of the good is Rs 10. Calculate the profit at each output level. Find the profit maximising level of output.
Output | TC (Rs.) |
---|---|
0 1 2 3 4 5 6 7 8 9 10 |
5 15 22 27 31 38 49 63 81 101 123 |
Quantity Sold |
Price | TC | TR = P x Q | Profit = TR - TC |
---|---|---|---|---|
0 | 10 | 5 | 10x0=10 | 0 - 5 = -5 |
1 | 10 | 15 | 10x1=10 | 10 - 15 = -5 |
2 | 10 | 22 | 10x2=20 | 20 - 22 = -2 |
3 | 10 | 27 | 10x3=30 | 30 - 27 = 3 |
4 | 10 | 31 | 10x4=40 | 40 - 31 = 9 |
5 | 10 | 38 | 10x5=50 | 50 - 38 = 12 |
6 | 10 | 49 | 10x6=60 | 60 - 49 = 11 |
7 | 10 | 63 | 10x7=70 | 70 - 63 = 7 |
8 | 10 | 81 | 10x8=80 | 80 - 81 = -1 |
9 | 10 | 101 | 10x9=90 | 90 - 101 = -11 |
10 | 10 | 123 | 10x10=100 | 100 - 123 = -23 |
Profit maximising output is where the difference between TR and TC is the maximum. This exists at 5 units of output, where firm is earning profit of Rs 12.
What is the supply curve of a firm in the long run?
The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?
Distinguish between a centrally planned economy and a market economy.
How does the imposition of a unit tax affect the supply curve of a firm?
A consumer wants to consume two goods. The prices of the two goods are Rs 4
and Rs 5 respectively. The consumer’s income is Rs 20.
(i) Write down the equation of the budget line.
(ii) How much of good 1 can the consumer consume if she spends her entire
income on that good?
(iii) How much of good 2 can she consume if she spends her entire income on
that good?
(iv) What is the slope of the budget line?
Questions 5, 6 and 7 are related to question 4.
What is the relation between market price and average revenue of a price-taking firm?
What is budget line?
Suppose there are 20 consumers for a good and they have identical demand functions:
d(p)=10–3pd(p)=10–3p for any price less than or equal to 103103 and d1(p)=0d1(p)=0 at any price greater than 103.
Suppose your friend is indifferent to the bundles (5, 6) and (6, 6). Are the preferences of your friend monotonic?
Can there be a positive level of output that a profit-maximising firm produces in a competitive market at which market price is not equal to marginal cost? Give an explanation.
What are the characteristics of a perfectly competitive market?
Distinguish between a centrally planned economy and a market economy.
How does the budget line change if the price of good 2 decreases by a rupee
but the price of good 1 and the consumer’s income remain unchanged?
Compute the total revenue, marginal revenue and average revenue schedules in the following table. Market price of each unit of the good is Rs 10.
Quantity Sold | TR | MR | AR |
---|---|---|---|
0 1 2 3 4 5 6 |
At the market price of Rs 10, a firm supplies 4 units of output. The market price increases to Rs 30. The price elasticity of the firm’s supply is 1.25. What quantity will the firm supply at the new price?
Comment on the shape of MR curve in case when TR curve is a
(a) Positively sloped straight line
(b) Horizontal straight line
Will a profit-maximising firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.
